Question

Show transcribed image textThe neutron interference pattern of figure P39.45 was made by shooting neutrons with a speed of 200 m/s through two slits spaced 0.10 mm apart. What was the energy, in eV, of the neutrons? What was the de Broglic wavelength of the neutrons? The pattern was recorded by using a neutron detector to measure the neutron intensity at different positions. Notice the 100mu m scale on the figure. By making appropriate measurements directly on the figure, determine how far the detector was behind the slits.
